1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Parapharyngeal space (PPS) meningiomas are rare extracranial tumors that can mimic more common PPS lesions. We report a case of a 23-year-old female who presented with a painless, progressive neck swelling and intraoral bulge. Imaging revealed a well-defined, homogeneously enhancing mass in the left PPS with encasement of the internal carotid artery, compression of the internal jugular vein, and widening of the hypoglossal canal with adjacent dural enhancement. Core biopsy showed meningothelial whorls and psammoma bodies. Immunohistochemistry was positive for EMA and progesterone receptor, negative for S-100, with a low MIB-1 index, consistent with a WHO Grade I meningioma expressing somatostatin receptors. The tumor was deemed unresectable due to complete vascular encasement, and the patient was treated with peptide receptor radionuclide therapy (PRRT), resulting in tumor regression. This case underscores the importance of including meningioma in the differential diagnosis of PPS masses and highlights PRRT as a viable option in select unresectable, receptor-positive cases.
